356 The Irish Naiutalisk December, 



Messrs. Chaster and Tomlin. A marked increase in the 

 number of Vertigoes was noted as soon as we left the lime- 

 stone, and every likely spot yielded V. antivertigo, V. pygmcea, 

 and V. angustior in dozens, with always a few specimens of 

 V. substriata. The last species seems much the rarest of the 

 genus in the district, with the exception, of course, of V. Lillje- 

 borgi. Large numbers of Pupa anglica of a very dark form 

 were taken with V- angustior on Gorteen Point and elsewhere, 

 none of the var. pallida^ which is usually so common in Ireland, 

 being seen at this spot. Our failure to find Pupa museoriim 

 alive was somewhat surprising, as Mr. Standen recorded it 

 from here in 1895. On Karawalla Point a colony of very high- 

 spired Helix virgata was found, many specimens being almost 

 scalariform, while the var. albicans was the chief form of colour 

 variation. A peculiar form of H. cricetomm was noticed at 

 Dog's Bay, the animal and shell having a distinct reddish- 

 purple tinge all over, which remains in the shell after the 

 animal has been extracted. On Gorteen Point some exceed- 

 ingly fine specimens of Aplexa hypnorum were collected, the 

 largest measuring 13mm. in height. After reading Dr. Scharff's 

 note on Helix tonnensis in the J.H., Aug., 1906, we were 

 naturally much interested in large heavy H. nemoralis from 

 the Dog's Bay deposits. Most of the H. aspersa from these 

 also showed the same tendency to heaviness. I collected a 

 small quantity of shells from these deposits which I have 

 handed over to Mr. A. S. Kennard, who, with Mr. R. Welch, 

 has in prepartion a paper on this subject. 



In the following list of species I have followed for con 

 venience Dr. Scharff's nomenclature, as given in the I.N.

List of Species. 



Vitrina pellucida, Miill. — Rather scarce — seen alive at Galway, 

 Dog's Bay, and on Inishniore. It was evidently too early in the 

 season for this shell. 



Hyalinia cellarla, Mull. — Common in all localities visited, including 

 Inisbmore and Inislimacdara. 



Hy. alliaria, Miller. — Not nearly so common as the last species, but 

 was taken sparingly at Kilbeg, Ballindooley, Clare-Galway, Ross, 

 and Ballynahincb ; and plentifully on Inisbmore. 



[Hy. Draparnaudi, Beck. — This species lias been recorded from Clare- 

 Galway and Inisbmore by Mr. Standen and Dr. Scharff, but we did 

 not obtain any specimens of it on the present occasion.]
